A tether ball is attached to a swivel in the ceiling by a light cord of length L. When the ball is hit by a paddle, it swings in a horizontal circle with constant speed v, and the cord makes a constant angle beta with the vertical direction. The ball goes through one revolution in time T. Assume that T, the mass m, and the length L of rope are known, derive algebraic expression for the tension FT in the...

A ball with a weight of 2 N is attached to the end of a cord of length 2 m. The ball is whirled in a vertical circle counterclockwise. The tension in the cord at the top of the circle is 7 N and at the bottom it is 15 N. (Do not assume that the speed of the ball is the same at these points.) a) Three students discuss the net forces on the ball at the top: Deante:...

The ball has a mass m and is attached to the cord of length I. The cord is tied at the top to a swivel and the ball is given a velocity. Show that the angle which the cord makes with the vertical as the ball travels around the circular path must satisfy the equation. Neglect air resistance and the size of the ball.
